What unit is resistance measured in?

• A. Volts (V)
• B. Amperes (A)
• C. Ohms (Ω)
• D. Coulombs (C)

Answer: (C)

Resistance is measured in ohms, which are represented by the Greek letter omega (Ω). This unit quantifies how much a material opposes the flow of electric current. When an electric current flows through a conductor, the resistance determines how much current will flow for a given voltage according to Ohm's law, which states that V (voltage) = I (current) x R (resistance). Therefore, knowing that resistance is measured in ohms helps in understanding and solving various electrical problems involving circuits. The other units refer to different electrical concepts: volts measure electric potential, amperes measure current flow, and coulombs measure electrical charge.
